7 To allwhom "it may concern:

Be it known" that 1,. JonnP. HARPER, 1a

of i/Vest, Virginia, have invented new and useful Improvements in Universal Valve,

Spring Compressors, of which the following 1s a specification. 1

This invention relates to means for com-- pressing the springs. of valves of internal vide a device which can be used for compressing the springs of all valve in the head motors including the type where the valve unit is carried by a cage.

Anotherobject of the invention is to make the device of few parts which are so arranged that the device is extremely simple in operation and can be manufactured to sell at low cost.

A further object of the invention is to make the parts, adjustable so that the de vice can be used on heads or cages of different Widths and different heights.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the appended claims.

Figure 1 is'a perspective view ofthe invention. i I

Figure 2 is a sectional view showing the same in use.

y Figu'reB is a sectional detail view through engaging member and the right, and the spring engaging member 4-,

which is slidably mounted on the handle. I

prefer to form the base 1 and upright 2 from i a single strip of material which is bent at 8 which hinges the handle 3 to the upright.

'of 'the limbs of the handle. her is slidably' connected with the handle.

The handle is adjusted in relation to the base by placingthe' pin 8 in any one of the pairs of holes 7. The handle :Bfiis formed ofa strip of material looped up'onitself with its extremitiesperforatedto receive .the pivot pin 8. The-member is also formed of a strip of metal bent into U-shape to embrace the handle and with its extremities bent upwardly, as at 4, to engage the inner faces Thus the mem- The bight of member 4- is provided with a cup-shaped depression 9 in, its under face which has a hole 10 in its center.

of the spring 11 of the valve 12, the stem of the valve passing through the opening 10. An opening 13 is formed in the basefor receiving the head of the valve and the walls of this opening are beveled sofas to provide.

This depresslon is adapted to receive theupper end a seat for the valve, as shown in Figure '2.

This seat is especially adapted for removing the spring and "by having the member 4" slidably mounted on the handle and the handle adjustable vertically on the upright the device can be used with various types and sizes of motors. The parts are so ar ranged that there is no danger of the spring thus injure the operator. '1

It is thought from the foregoing description thatthe advantages and novel features of my invention will be readilyapparent.

' I desire-it to be understood that I-may combination and arrangement of the several parts, provided that such changes fall with in the scope of the appendedclaims. c

hat- I claim is 7 1. A device of the class described compris ing a base, an upright connected therewith, a handle adjustably and pivotally connected with the upright and a spring engaging member slidably mounted on the handle.

2. A device of the class described conn prising a base, an upright connected there- -with, a handle adjustably and plvotally con nected with the upright and a spring engaging member slidably mounted on the slipping and causing parts to fly about and make changes in the construction and in" the handle, said member having a cup-shaped depression therein for engaging the spring and an opening at the center of the depression for receiving the valve stem.

3. A device of the class described comprising a base, an upright connected there with, a handle adjustably and pivotally connected with said upright,- a valve spring engaging member slidably mounted on the handle and said base having an opening therein having beveled walls "for forming a seat for a valve head.

at. A device of the class described comprising a base, an upright connected With the base and being of channel shape in cross section, the flanges of said upright having a plurahty of holes thereln, a handle of U-shape,

a plvot pin passing through the extremities ot the handle and engaging any one of the pairs 01'. holes in the upright, a valve springengaging member of U-shape having its limbs embracing the limbs of the handle, the bight of said member having a cup-shaped recess therein for receivirig the end of the spring and an opening at the center of the recess for receiving the valve stem.

In testimony whereof I aflix my signature.

JOEL P. HARPER.
